Samsung SSD 860 EVO - SANDRA And ATTO Disk Benchmark

Next we ran SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on clean drives after the test system reached and idle state. Average read and write performance metrics are detailed below.

ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5KB through 64MB transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, or the like.

We saw more of the same in the ATTO Disk Benchmark. The Samsung SSD 860 EVO put up some of the best read and write scores we have seen from a SATA-based drive, regardless of transfer size.
